From the Options menu for each portal, you can see how many times your portals have been viewed. Anyone that enters a portal, either when they're creating and editing it or after they share it (with or without a required login or access code) and the page is opened or refreshed, is counted as a viewer.
To see the number of times a portal has been viewed:
Access the Portals dashboard from the Widen Collective
View the options for your desired portal
Select Portal views from the menu
Define the date range
The number of views for each date as well as the total number of views displays in the table.
